Not interested in a preorder, but I would certainly buy at least one if/when you start rolling out working units.
I can understand your hesitation in an industry full of scamsters. Everyone who wants one of these will get one, pre-order or not

Would you guys consider a kickstarter project?
It has crossed my mind looking at the various funding tools we have access to, though if we were going to go that route I would like to see it be a bitcoinstarter type of campaign. I havn't seen a platform for Litecoin yet (hint hint

).
